紫茎泽兰叶水提液对七种乡土植物幼苗生长和叶绿素的化感影响
Allelopathic effects of aqueous extract of Ageratina adenophora on seven native plant seedlings in growth and chlorophyll
摘要
Abstract
Ageratina adenophora was used as the donor, and seven kinds of native plants were used as the receptor, they were Pinus massoniana, Cunninghamia lanceolate, Broussonetia papyifera, Castanea mollissima, Zanthoxylum bungeanu, Camellia oleifera, Pyracantha fortuneana, respectively.We studied the allelopathic effects of Ageratina adenophora aqueous extract solution on chlorophyll content and growth of seedlings of tested plants.The results are as follows: (1) A.adenophora aqueous aqueous extract solution at low concentration can improve the chlorophyll a, chlorophyll b and total chlorophyll contents of Zanthoxylum bungeanu and Pyracantha fortuneana, but the effects on chlorophyll of the other five species was not significant.Ageratina adenophora aqueous extract solution at high concentration reduced the chlorophyll a, chlorophyll b and total chlorophyll contents of Cunninghamia lanceolate, Castanea mollissima, Broussonetia papyifera significantly.The chlorophyll b of Pyracantha fortuneana decreased significantly, while the chlorophyll b of Pinus massoniana increased on the contrary, there was no significant influence on Castanea mollissima and Zanthoxylum bungeanu. (2) We measured the receptor plant growth parameters and found that, Ageratina adenophora aqueous extract solution at high concentration had significant inhibitory effects on all growth parameters of the six receiver plants except for Castanea mollissima.Ageratina adenophora aqueous extract solution at low concentration could improve the ground diameters and crown widths of Pyracantha fortuneana, Zanthoxylum bungeanu and Cunninghamia lanceolata, but had no significant effects on growth parameters of the other four species.关键词
